The Croatian government on Monday decided to ban flights of Russian-owned, Russian-registered, or Russian-controlled aircraft in Croatia's airspace.

Transport Minister, Oleg Butkovic, said that the ban refers to all arrivals, departures, and transit by planes of Russia’s airline companies, as well as all aircraft “owned, rented, or operated” by Russian nationals. Humanitarian flights, flights for rescue operations with special permits, as well as flights in extraordinary circumstances such as repatriation flights are exempt from the ban.

Russia’s flag carrier, Aeroflot, operates year-long flights to Zagreb and Dubrovnik, and a seasonal service to Split.

The government also said they moved to set up a crisis management team for what they called “an intervention plan” to ensure the security of gas supplies, and another task force “for monitoring the security of the supply of petroleum products on the Croatian market.”

Croatia uses between 2.5 and 3 billion cubic meters of natural gas every year, and roughly 60 percent of its needs are covered by Russian imports, provided mainly by Russia’s giant Gazprom, and delivered via local distributor PPD.
